vscode之使用了babel_node，请问调试时改如何配置呢

Question

已知默认的配置为

"version": "0.2.0",
    "configurations": [
        {
            "type": "node",
            "request": "launch",
            "name": "启动程序",
            "program": "${workspaceRoot}/bin/www",
            "cwd": "${workspaceRoot}"
        },
        {
            "type": "node",
            "request": "attach",
            "name": "附加到进程",
            "port": 5858
        }
    ]
自定义npm start的命令为 `babel-node ./bin/www --presets es2015,stage-2` 请问该如何改这个配置参数呢？
